OBJECTIVE: Surface mechanomyography (sMMG) can measure oscillations of the activated muscle fibers in three axes (i.e., X-, Y-, and Z-axes) and has been used to describe motor unit activation patterns (X-axis). The application of blood flow restriction (BFR) is common in exercise studies, but the cuff may restrict muscle fiber oscillations. Therefore, the purpose of this investigation was to examine the acute effects of submaximal, fatiguing exercise with and without BFR on sMMG amplitude in the X-, Y-, and Z-axes among female participants...
